SSD write endurance considered sufficient
With the advent of flash memory with average cell life spans approaching one million writes, it seems that the old fallacy of flash memory being less durable than old school platters is finally crumbling — even in the most ridiculous of scenarios. Magnus Deininger has done an awesome simulation of the expected drive integrity at sustained full SATA 3.0 level throughput. A now not-so-uncommon SSD with a capacity of 256 GB will now keep its integrity above 90 % for more than 9.4 years in this vastly unrealistic scenario. In other words; your mirrored NAND flash in your enterprise SAN is pretty damn safe.
